Slimani slays the Dragons again

In three previous matches in 2016 alone, the Algeria international had netted five times.

Here, he met the teasing, curling cross of the excellent Mahrez, diving towards the ball at the back post to head past a reluctant Iker Casillas.

It is his third goal in four games for the Foxes, all of which have been scored with his head.

Just as in their Premier League title-winning campaign, Leicester were happy to concede both territory and possession

Leicester, last season’s surprise Premier League champions, have made an uncertain start to the defence of their title, losing three of their opening six games and conceding four goals in defeats by both Liverpool and Manchester United.

Yet the template that brought success last season – a deep, solid backline and pacey counter-attacks – was once again employed with success at a raucous King Power Stadium.

After seeing his side leak three goals to corners at Old Trafford on Saturday, Leicester boss Claudio Ranieri preferred Luis Hernandez to Danny Simpson at right-back, but it was centre-halves Wes Morgan and Robert Huth who impressed.

At the other end, Mahrez caused trouble on the right in the first half, Vardy explored the channels and Slimani barely stopped running.

Porto pressure comes too late

For two-time European champions Porto, a domination of the second half – they had eight attempts on goal to Leicester’s three – only brought serious pressure in the dying moments.

Indeed, until a frantic, backs-to-the-wall final 10 minutes, a low save from Hector Herrera’s long-range effort was the biggest test of the returning Kasper Schmeichel in the Leicester goal.

But, as Porto pressed, the Foxes were pushed deeper and goalmouth confusion became commonplace, with Corona’s back-post effort deflecting off Marc Albrighton and on to the woodwork.

As the tension increased, a flurry of late corners was not enough for Porto to improve a dismal record in England that extends to 17 games without a win.

What they said

Leicester boss Claudio Ranieri: “We suffered in the last 10 minutes but it was important to win. Concentration was high, we were resilient, I’m very happy.

“We played with our spirit tonight. The last pass wasn’t always there, but Riyad Mahrez made one fantastic pass for Slimani.”

The stats you need to know

Leicester City are the 10th club to represent England in the Champions League and the first to start their debut season with two victories from their first two matches.

Islam Slimani (Leicester, Sporting CP) became the first player from Algeria to score for multiple sides in the Champions League.

What’s next?

Leicester, who have won only two of their six Premier League games this season, host Southampton on Sunday at 14:15 BST. Their next Champions League fixture is at home to FC Copenhagen on Tuesday, 18 October, when Porto travel to Club Brugge.
